Hybrid tea rose variety &#39;POULnew&#39;

ABSTRACT

A new hybrid tea rose plant which has abundant, large, cream white, fragrant flowers and attractive, dark-green foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

[0001] The present invention constitutes a new and distinct variety of hybrid tea rose plant which originated from a controlled crossing between ‘Peauduce’ (non-patented) and an unnamed, non-commercialized seedling (non-patented). The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULnew’.

[0002] The new rose may be distinguished from its seed parent, ‘Peauduce’, by the following combination of characteristics:

[0003] 1. The seed parent has light yellow blooms; whereas, ‘POULnew’ has cream white blooms;

[0004] 2. The growth habit of the seed parent is wider and more shrubby when compared to ‘POULnew’.

[0005] The new variety may be distinguished from its pollen parent, an unnamed seedling, created by the same inventors, by the following combination of characteristics:

[0006] 1. The pollen parent is a climbing rose while ‘POULnew’ is shorter and shrubby;

[0007] 2. The pollen parent has clear yellow blooms; whereas, ‘POULnew’ has cream white blooms;

[0008] 3. The pollen parent has semi-double blooms compared to the double blooms of ‘POULnew’.

[0009] The objective of the hybridization of this rose variety for garden use was to create a new and distinct variety with unique qualities, such as:

[0010] 1. Uniform and abundant flowers;

[0011] 2. Vigorous and compact growth;

[0012] 3. Fragrance;

[0013] 4. Continuous blooming;

[0014] 5. Disease resistance.

[0015] This combination of qualities is not present in previously available commercial cultivars of this type and distinguishes ‘POULtnew’ from all other varieties of which we are aware.

[0016] As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

[0017] ‘POULnew’ was selected in spring 1989 by the inventors as a single plant from the progeny of the aforementioned hybridization.

[0018] Asexual reproduction of ‘POULnew’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August 1989. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULnew’ are true to type and are transmitted from one generation to the next.
